1. A DATA COMMUNCATION SYSTEM COMPRISING A PLURALITY OF SWITCHING CENTERS, A PLURALITY OF TRUNKS INTERCONNECTING SAID SWITCHING CENTERS FOR TRANSFERRING MESSAGES EACH HAVING A PLURALITY OF DATA BITS BETWEEN SAID SWITCHING CENTERS, MEANS FOR CONNECTING A SOURCE OF DATA TO A FIRST ONE OF SAID SWITCHING CENTERS, SAID FIRST SWITCHING CENTER COMPRISING STORAGE MEANS, MEANS FOR TRANSFERRING MESSAGES IN BULK FORM FROM SAID SOURCE TO DISCRETE PORTIONS OF SAID STORAGE MEANS, MEANS FOR TRANSFERRING ONE BIT OF EACH STORED MESSAGE TO CORRESPONDING PRESELECTED TRUNKS IN SELECTED DISCRETE TIME INTERVALS OF A RECURRENT CYCLE OF TIME INTERVALS, AND MEANS FOR TRANSFERRING TO SAID STORAGE MEANS ONE BIT OF EACH INCOMING MESSAGE TRANSMITTED OVER SAID TRUNKS IN OTHER SELECTED DISCRETE TIME INTERVALS OF SAID RECURRENT CYCLE.
